where you may specify between 1 to 16 lists of items (1 to 10 items per list) to pseudocategorize per template call. If you have more items to pseudocategorize, just do more template calls with up to 16 lists of items (1 to 10 items per list) for each of them. If you want links to the items to pseudocategorize, you must make it explicit with double square brackets (it is not done automatically to allow for up to 10 items per list, if it was done automatically we could have only one item per list.)

This will categorize the category with uncategorizable items (view source only) in the hidden category

with a message given via the template specifying the pseudocategorized items, thus providing the required information for sysops or administrators to actually categorize the items accordingly (unless they think of better categorizations.)
